Why no yellow in powershell and posh git

It turns out PowerShell's console renders System.ConsoleColor.DarkYellow as white:

[Enum]::GetValues([ConsoleColor]) | %{ Write-Host $_ -ForegroundColor $_ }

Using bold yellow instead, which renders with System.ConsoleColor.Yellow, works:

git log --pretty='%C(bold yellow)%h%Creset %s' --abbrev-commit
